How to buy vegetables, how to choose all kinds of vegetables

If it is some green leafy vegetables, it depends on whether they have been eaten by insects, and the kind with wormholes is a green vegetable.

In some places, vegetable markets have vegetable pesticide residue testing, as long as it does not exceed the standard, the harm is not great, and a small number of vegetable growers use that kind of highly toxic pesticides, which is very harmful to people's health.

Roadside stalls have the opportunity to buy green vegetables, and the dishes without pesticides are in poor condition.

Just like this, eggplants are not sprayed, there is a big difference in appearance and size, and the roadside stalls buy them, and five cost one piece of five, while the vegetable market costs at least four or five yuan a catty.

Here are a few things to keep in mind when picking vegetables:

1) Don't buy vegetables with unusual colors. Fresh vegetables are not as bright as possible, such as when buying cherry radishes, check whether the radish has faded;

If you find that the green color of dried beans is brighter than others, you should choose carefully.

2) Don't buy vegetables that are abnormally shaped. Stale vegetables have abnormal forms such as wilting, drying, damage, lesions, and insect erosion; Some vegetables will grow into deformities due to the artificial use of hormones.

3) Don't buy vegetables that smell abnormal. In order to make some vegetables look better, unscrupulous traders soak them in chemicals such as sulfur and nitrate, which have a peculiar smell and are not easily washed off.
